When use the media player to play I don't see a progress bar so I can't tell how far the song has reached. At some time when a song was on pause, I noticed a progress bar, but i don't know how it got there, and I don't see an option to have it or not

Tap the screen, and the progress bar will appear for a few seconds. (Tap, don't click)
